Definitions

  • the invention relates to a torsional vibration damper, in particular a divided flywheel, with at least two flywheels which can be rotated against the resistance of at least two deformable energy storage elements, in particular helical compression springs, which are coupled to one another by at least one coupling device which, when a first energy storage element deforms, in particular is relaxed, a targeted entrainment of a second energy storage element is effected and has at least one first and one second entraining device.
  • a preferred exemplary embodiment of the torsional vibration damper is characterized in that the coupling sliding elements are each formed by the sliding element of a plurality of sliding elements, which is first moved together with the associated energy storage element when the torsional vibration damper is subjected to tensile stress.
  • the energy storage elements are preferably arcuate helical compression springs.
  • the coupling sliding elements are preferably sliding shoes which are arranged in the radial direction between the associated energy storage element and the primary flywheel mass or the input part of the torsional vibration damper.
  • the coupling sliding elements are arranged between two driver fingers, which extend from the coupling device.
  • the coupling sliding elements can also be provided with a hole into which a driver finger engages, which extends from the coupling device.
  • FIG. 6 shows the coupling ring from FIG. 5 in a top view
  • Figure 8 shows the coupling ring in front view
  • Figure 10 shows a coupling ring according to a second embodiment in perspective
  • Figure 11 shows the coupling ring from Figure 10 in plan view
  • Figure 12 is a sectional view taken along the line XII-XII in Figure 11 and 13 shows an enlarged detail XIII from FIG. 11.
  • the torsional vibration damper shown in different views in FIGS. 1 and 2 forms a divided flywheel 1 which has a first or primary flywheel mass 2, which can be fastened to an output shaft of an internal combustion engine, not shown, and a second or secondary flywheel mass 3.
  • a friction clutch is attached to the second flywheel 3 with the interposition of a clutch disc, via which an input shaft of a transmission, also not shown, can be engaged and disengaged.
  • the primary flywheel mass 2 is also referred to as the input part of the torsional vibration damper.
  • the secondary mass 3 is also referred to as the output part of the torsional vibration damper.
  • driver fingers 67, 68 which extend from the coupling ring 64, engage around a coupling sliding element 71 radially on the outside.
  • the coupling sliding element 71 is coupled to the helical compression spring 7.
  • eight sliding shoes 74 to 81 are coupled to the helical compression spring 7.

Abstract

L'invention concerne un amortisseur de vibrations en torsion, en particulier un volant d'inertie divisé, qui présente au moins deux masses d'inertie (2, 3) qui peuvent tourner en opposition à la résistance d'au moins deux éléments déformables (7, 8) d'accumulation d'énergie, en particulier des ressorts hélicoïdaux de compression accouplés l'un à l'autre par au moins un dispositif d'accouplement (24), qui, lorsqu'un premier élément (7) d'accumulation d'énergie se déforme et en particulier est détendu, a pour effet un entraînement contrôlé d'un deuxième élément (8) d'accumulation d'énergie et qui présente au moins un premier et un deuxième dispositifs d'entraînement (27, 28). Pour éviter des secousses indésirables lors du fonctionnement d'un véhicule automobile équipé de l'amortisseur de vibrations en torsion, le premier dispositif d'entraînement (27) est accouplé au premier élément coulissant d'accouplement (32) qui lui-même est accouplé au premier élément (7) d'accumulation d'énergie, et le deuxième dispositif d'entraînement (28) est accouplé à un deuxième élément coulissant d'accouplement (32) qui lui-même est accouplé au deuxième élément (8) d'accumulation d'énergie.
